Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.
In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of indicated technical features. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.
The scheduling method based on the automobile function service can be applied to the system architecture environment shown in fig. 1. The functional service 101, the atomic service 102, and the operating environment 103 communicate with each other through a network, where the network may be a CAN network, an ethernet network, and the like, and the application may be selected according to characteristics of each network. Optionally, middleware 104 for signal conversion may be further included to convert the CAN signal and/or the CANFD signal into a signal format supported by the application program interface.
The method comprises the steps of obtaining a currently running functional service, wherein the functional service comprises one or more atomic services; detecting whether the functional service generates a timing conflict when the atomic service is called; and if so, matching the functional service with a scheduling time sequence table to obtain a matching result corresponding to the functional service, and scheduling the functional service and/or the atomic service according to the matching result.
In one embodiment, as shown in fig. 2, a scheduling method based on car function service is provided, which is described by taking the method as an example applied to the system architecture environment in fig. 1, and includes the following steps:
The functional services refer to automobile services with higher functional complexity, and relate to logic control algorithms with high algorithm complexity and the like. Atomic services refer to a series of operations with minimum granularity on business, and are characterized by loose coupling, relative independence and being some lower-layer services such as I/O services, storage services and the like, and more complex functional services can be realized through the combination of one or more atomic services. Both functional services and atomic services belong to the services of automobiles.
Specifically, the method includes the steps of obtaining function services currently operated by an automobile and atomic services called by the function services, wherein in the service operation process, signal interaction usually exists between a function service module and an atomic service module which are connected and communicated with each other, and the calling relation between the function services and the atomic services can be known by verifying whether the data types and/or signal names of signals are matched or not.
Referring to fig. 3, a schematic diagram of a call process of a functional service and an atomic service is shown, wherein it may be detected whether the same atomic service is called by at least two functional services at the same time, and/or whether the same atomic service is already called or occupied by another functional service when called by any functional service, so as to determine whether a timing conflict (call conflict) may be triggered.
And 203, if so, matching the functional service with a scheduling time sequence table to obtain a matching result corresponding to the functional service, and scheduling the functional service and/or the atomic service according to the matching result.
The scheduling time sequence table can be preset in an automobile or acquired from a cloud database, and is mainly configured with scheduling priority rules and used for preventing time sequence disorder and service calling conflict when service scheduling is carried out according to a certain priority sequence.
Specifically, the scheduling priority rule may set the priority of each functional service and/or atomic service in order of legal requirements, hardware enforceable states, functional policy requirements, personal safety requirements, vehicle safety requirements, user frequently-used functional requirements, user infrequently-used functional requirements, non-user functions, and the like. And matching the running functional service with the scheduling time sequence table to obtain the priority of the running functional service and the priority of the called atomic service.
It can be understood that in the process of scheduling the functional service, the service with high priority degree can be ensured to normally run, so as to avoid generating driving risk to cause the out-of-control of the automobile.
In the scheduling method based on the automobile function service, whether the calling conflict of the atomic service possibly exists among a plurality of function services is judged by acquiring the currently running function service and detecting whether the plurality of function services call the same atomic service; and if so, matching the functional service with a scheduling time sequence table to obtain a matching result corresponding to the functional service, and scheduling the functional service and/or the atomic service according to the matching result so as to enable scheduling execution of the automobile service to have time sequence. By the scheduling method based on the automobile function service, the automobile function service is subjected to time sequence management and scheduling, the redundancy among the function service modules is reduced, the time sequence disorder and the service conflict of the function service are avoided, and the time sequence of the automobile function service and the safety of the driving process are improved.
In one embodiment, the matching the functional service with the scheduling schedule includes:
and matching the priority of the currently running functional service with the scheduling time sequence table, wherein the scheduling time sequence table comprises priority information, and the priority information is configured according to the type information of the functional service and/or the atomic service.
In one embodiment, before the matching the functional service with the scheduling timing table, the method further includes:
judging whether the functional service is a concurrent service or not;
if so, controlling the functional service to perform concurrent operation;
if not, performing priority matching on the currently running functional service and the scheduling time sequence table to obtain priority information of each functional service, and scheduling the functional service according to the priority information.
The concurrent service refers to a service capable of supporting multiple services to run simultaneously, and it should be noted that the concurrent service is not equivalent to parallel, and the simultaneously running services may occur at the same time or may occur and keep running at multiple times within a period, and the essence is multiplexing of a central processing unit among multiple programs, so that the running efficiency of the service can be improved.
Specifically, if the currently running functional service supports concurrent running, it indicates that the precedence scheduling for the atomic service can occur in parallel, and the functional services do not affect each other.
If the currently running functional services do not support concurrent running, the services have stronger time sequence limitation, priority matching needs to be carried out on the currently running functional services and the scheduling time sequence table to obtain priority information of each functional service, and the functional services are scheduled according to the priority information.
Preferably, if the currently running functional service does not support concurrent running, conflict service screening may be performed, specifically, the functional service and the atomic service in which scheduling conflict occurs may be determined according to a signal of interaction between the functional service and the atomic service, and priority matching may be performed on the determined functional services, so as to improve service scheduling efficiency and avoid matching all services with the scheduling schedule.
In one embodiment, the scheduling the functional service according to the priority information includes:
comparing the priority according to the priority information of the functional service;
and controlling the functional service with higher priority to run, and suspending the functional service with lower priority to run.
Illustratively, after the priority of the front functional service and the priority of the rear functional service are compared, if the priority of the rear functional service is higher, the front functional service is suspended or stopped to run, and the rear functional service is run; if the priority of the former functional service is higher or the same as the priority of the latter functional service, the operation of the former functional service is continuously maintained, and the operation of the latter functional service is suspended or stopped.
In one embodiment, if the functional service is a concurrent service, the method further includes:
detecting whether the functional service has a concurrent flow conflict or not;
and if so, performing priority matching on the currently running functional service and the scheduling time sequence table to obtain the priority information of each functional service, and scheduling the functional service according to the priority information.
In addition to a time sequence conflict of atomic service calling, a concurrent flow conflict may also be generated during service operation, where the concurrent flow conflict refers to a conflict that may be generated during the operation of the concurrent service, and for example, a scheduling conflict of high voltage power on and off exists between high voltage maintenance and vehicle charging, and the high voltage power off may cause charging abnormality, so that the priority of the high voltage power off maintenance may be configured to be higher than the priority of the vehicle charging, and the vehicle charging function service may be interrupted during the high voltage power off maintenance, while the vehicle charging may not affect the high voltage power off maintenance service. For the scheduling policy, reference may be made to the scheduling control for the non-concurrent service in the foregoing embodiment, which is not described herein again.
It should be noted that, when the functional service is running or scheduled, the running data of the functional service may be compared with relevant national and/or international standard specifications, and if the running data exceeds the standard specifications, the running of the functional service should be prohibited.
In one embodiment, the method further comprises the step of scheduling the control strategy of the concurrent service across the domains:
it should be noted that, in the current architecture of the automotive domain control system, a plurality of control domains are divided, and different control domains are responsible for providing different functions, so that the priority problem also needs to be considered when the cross-domain functional service scheduling is faced.
Illustratively, the control policy for scheduling concurrent services across domains may be:
1. two or more parts with functions related to a power domain are used as main control, and a whole vehicle domain controller is selected as the main control in a centralized manner;
2. preferentially concentrating the sub-components to the function master control to judge, rather than judging by the sub-component which runs first in time sequence, and preferentially selecting the sub-component with higher priority as the master control;
3. in a scene which does not meet the enabling condition of a certain subsystem, the subsystem is temporarily set as a master control;
4. if the two functions are allowed to be concurrent, no obvious master control unit may be provided.
In one embodiment, the detecting whether the functional service generates a timing conflict when the atomic service is invoked includes:
obtaining a first signal of the atomic service and a second signal of the functional service, and determining whether the same first signal corresponds to at least two second signals
If so, the functional service has a time sequence conflict when calling the atomic service;
if not, the functional service does not have a time sequence conflict when calling the atomic service.
The "first" and "second" in the first signal and the second signal are merely for convenience of description, and are distinguished in terms of names, and no limitation is made to the number relationship, master-slave relationship, sequence relationship, or other attributes.
Specifically, in the operation process of the automobile service, signal interaction usually exists between the function service module and the atomic service module which are connected and communicated with each other, and the calling relationship between the function service and the atomic service can be known by verifying whether the data type and/or the signal name of the signal are matched.
Illustratively, referring to fig. 3, if a first signal of an atomic service corresponds to a second signal of two functional services (including data type correspondence and/or signal name correspondence of a signal, etc.), it indicates that the atomic service is called by the two functional services.
It should be noted that there may be one or more atomic services and functional services in the detection process, which are not limited herein, for example: the existence of any one or more first signals in the plurality of atomic services corresponding to any one or more second signals in the plurality of functional services indicates that the plurality of atomic services are simultaneously called by the plurality of functional services.
In one embodiment, the scheduling method further includes:
constructing a data flow framework for automobile control according to the atomic service and the functional service;
collecting automobile operation data carried by the first signal and the second signal in the data flow frame;
and scheduling the atomic service and/or the functional service according to the automobile operation data so as to control the operation of the vehicle.
The data flow framework is used for indicating a communication relationship (data transmission relationship) between modules of an automobile service in an operation process, the automobile operation data includes an operation state of an automobile component, and the automobile component may be some electronic control units or control systems, such as BMS (Battery Management System), MCU (micro controller Unit), DCDC converter and other components strongly related to driving and power.
Specifically, a data flow frame is constructed according to relevant information such as connection communication relation, signal interaction transmission and the like of atomic service and functional service, signals and data transmitted in the data flow frame are collected and analyzed, corresponding scheduling and operation control are carried out, and parameter and algorithm optimization and expansion are carried out according to automobile operation data collected in real time aiming at different driving conditions.
Illustratively, in the process of service scheduling, some services may be out of control or fail, and thus certain driving risks may be generated. Therefore, the operation control can be carried out according to the collected automobile operation data, and the operation control comprises the following steps: and carrying out self-adaptive torque adjustment according to the information of the driving mode, the state of the power domain component, the energy of the whole vehicle and the like acquired in real time, such as torque transfer of front and rear shaft torques according to the working conditions, avoiding plans, whole vehicle posture maintenance during tail flicking and slipping and vehicle power stability control, so as to ensure driving safety.
In addition, the function service and/or the atomic service can be updated respectively, and the corresponding service interface is set, so that iterative incorporation of new functions is realized, and the change of the whole system architecture is avoided.
It should be understood that, although the steps in the above-described flowcharts are shown in sequence as indicated by the arrows, the steps are not necessarily performed in sequence as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
